In 1875, Norwegian naval rank flags were again revised.
The old practice of flying the 1844 war ensign from different masts according to rank was
no longer practical as steam replaced sail and warships' sailing rig was reduced or
eliminated. The 1875 saluting instructions introduced four new flags with insignia in the
lower fly according to rank: crossed batons for the commanding admiral of the Navy and
three stars, two stars or one star for full admirals, vice-admirals and rear-admirals
respectively.

The 1858 senior officer's flag was now to be used as the
commodore's broad pennant, and a new pennant with the union mark at the hoist was
introduced for senior officers. In 1898, this pennant was changed to one in which the
union mark appeared in the top hoist only. The plain red 1858 pennant for warrant officers
was retained. A similar range of rank flags was introduced at the same time for
Sweden.

The 1898 rank flags were abolished and replaced by
"pure" national designs when the union between Norway and Sweden was dissolved
in 1905.
